Title: Method of quenching of coke
Inventor: SHERESHNEVSKY JOSIF SOLOMONOVI
IPC: C10B39/02
Filed: 1964-01-29
Abstract: One or more volatile hydrocarbons are passed over the surface of hot coke to pyrolyse the hydrocarbons and quench the coke.  The coke may be allowed to fall down a reaction vessel while the hydrocarbons pass in counter-current thereto, the contact times being 0.3 to 1.0 second.  The hydrocarbons may be methane, propane, fractions obtained by the pyrolysis of coal or oil, or low octane gasoline.  Four specific examples are described.  In one, in which methane was used, the product included 70 vol. per cent hydrogen and 22 vol. per cent carbon monoxide.  In another, in which propane was the quenching agent, the effluent gas contained (volume per cent), 25 to 28 ethylene, 7 to 8 propylene and 0.5 to 0.7 butylene; in a third (quenching agent a pyrolysis fraction of solid fuel), the following hydrocarbons were obtained (per cent by weight): ethylene 27.2 to 28.5, propylene 13 to 17.2, butylene 4 to 6, butadiene 4 to 6.2, benzol 4 to 6.8, toluene 1.9 to 3.1 and xylene up to 4.5.  In the fourth example (quenching agent low octane gasoline), methane and hydrogen accounted for 30 weight per cent and olefines 40 weight per cent, tars 25% and coke 5% completing the yield. The effluent gases are at 750 DEG  to 900 DEG  C., and may be used to preheat the hydrocarbons.

Title: Process of separating meta-substituted alkyl phenols from mixtures of meta and para-substituted alkyl phenols
IPC: C07C37/18
Filed: 1942-04-01
Abstract: 557,519. Alkyl phenols. SHELL DEVELOPMENT CO. April 1, 1942, No. 4337. Convention date, April 1, 1941. [Class 2 (iii)] Meta-substituted alkyl phenols are separated from a mixture of meta and para alkyl phenols by alkylating the mixture with a limited amount of alkylating agent approximately equal to n mols. per mol. of para isomer plus m mols. per mol. of meta isomer present where m and n are the number of readily alkylatable positions in the meta and para isomers respectively, followed by a fractional distillation. The effect of the alkylation with a limited amount of alkylating agent is stated to be the production of a product from the para isomer which contains one alkyl group more than the product from the meta isomer. The alkylation is carried out under the usual conditions using olefins, alkyl chlorides, or alcohols. Examples of each of these types of compounds are mentioned. Catalysts or condensing agents may also be present as also may if desired solvents. In an example to a xylenol fraction boiling at 211‹ C. and containing approximately 315 grains of 2 : 5 - dimethyl phenol and 1,485 grains of 2 : 4 - dimethyl phenol there was added 1,050 grams of tertiary butyl chloride, 240 grams of ferric chloride and 4,500 grams of carbon dilsulphide. The mixture was refluxed for 8 hours and worked up by distillation. The amount of unreacted 2 : 5-dimethyl phenol recovered was 85 per cent. of the amount present in the original mixture. The 2 : 4 : 6- trialkyl phenols obtained are valuable antioxidants for use in cracked gasoline and other petroleum products.
